It's Star Wars. Being out of print doesn't at all mean that it's unavailable. The '97 SE VHS tapes are out of print too but that doesn't make them difficult to find.
Anyhow, yeah I sorta noticed that they've more or less replaced this series with the new one. That's a bit of a shame, really, because this series was really well received when it came out. Personally I kinda see the new one replacing the old one as almost a spit in the face to Tardakofsky.
